We all are familiar with addition of decimal numbers .Similar operation can be performed on  binary numbers. In fact binary arithmetic is much simpler than decimal, since only two digits are involved ,0 and 1.Binary arithmetic is essential part of all the digital computers .let’s go for it,

Some which you need to know first is,

In first three rows, there is no carry means, carry is zero(c=0 ),while in last row carry is generated (c=1) . As similar in decimal addition ,this carry will be added to the next higher binary position.As shown in the example,

1 0 1 0 + 0 1 0 1 = ?

1   0   1   0       = (10)10
0   1   0   1       =  (5)10

NEXT EXAMPLE,

See another example to clearify more, Adding two binary numbers? Step by step shown below.
1 1 1 0    + 0 1 1 1   =  ?

In this way we can add two binary numbers.
